“A senior government minister in Australia has announced that her lesbian partner is pregnant. Finance Minister Penny Wong said in a statement Tuesday that her partner, Sophie Allouache, had conceived through in-vitro fertilization and is expecting her first child in December.”

The announcement comes as pressure mounts on Prime Minister Julia Gillard to support overturning her center-left Labor Party’s ban on gay marriage. The policy change will be voted on its annual national conference in December.
